NXP Semiconductors TDA5051A Modem IC
NXP Semiconductors TDA5051A is a Power Line Modem IC dedicated to Amplitude Shift Keying (ASK) transmission by means of a home power line network at 600 baud or 1200 baud data rate. The NXP TDA5051A operates from a single 5V supply and enables easy connection to standard microcontrollers, including the NXP LPC11xx series. TDA5051A PLM IC employs control logic that provides full digital carrier generation and shaping and a high clock rate of 6-bit digital to analog converter that provides rejection of aliasing components. This NXP power line modem IC contains a fully integrated output power stage with overload protection. The receiver employs an AGC (Automatic Gain Control), 8-bit analog to digital converter and narrowband digital baseband filtering and digital demodulator. The modulation and demodulation frequency is set by clock source from microcontroller or on-chip crystal oscillator.
